LT4 Nitrous Express Nitrous System with Billet LT4 Supercharger Lid w/ No bottle


Model Number: 20939-00
Nitrous Express

This Billet LT4 Supercharger Lid replaces the upper supercharger lid on all GM LT4 Superchargers for a quick and clean install. Nitrous and fuel are injected into each cylinder from inside of the supercharger lid, providing direct port style distribution. Systems come standard as a single stage with jetting for 100 to 300WHP. This lid is made from a solid piece of billet aluminum with 1/8NPT machined directly into the lid, which makes it easy to add a direct port water/methanol later on.

System Includes:

Billet aluminum and carbon fiber lightning solenoids

Billet aluminum Lightning 500 bottle valve

Stainless steel braided lines

Stainless steel bottle brackets

Wiring, switches, and every nut, bolt, and connector needed to install the system
